Research direction
Review the test class NegativeAcksTest in the Apache Pulsar repository, focusing on testNegativeAcksWithBatchAckEnabled. Analyze the timeout setting and check the issue comments for any previous investigation. Attempt to reproduce the flakiness locally and consider if a simple timeout increase resolves it or if a deeper fix is needed.
